Dometic PLB40 - Warning Light - Short Circuit?

Anyone else have a short circuit failure on the USB port on the Dometic PLB40?

I have been using mine for 4 or 5 years flawlessly.
Tried hooking up my Uniden SDS-200 scanner and raspberry PI 5V usb connector to the Dometic and it went into fault mode.

No fuses blown...short circuit triggered.

Been running this same setup off the 12v lighter in the truck for several years now.

The Dometic normally powers my Engel fridge 24/7 and when it’s in my truck it is recharged via Solar...been doing this for years. Additionally it was keeping my Blackvue Battery recharged when connected to Solar.

IMHO this should not have short circuited the PLB40.

this configuration is running via 12v cig lighter on my truck 24/7.

I called Dometic and emailed their customer support.

they said they would email me back after I got if the phone with them but they never did.

 

Raspberry PI fried the board.

 

Nope. Circuit Board Fried where the USB circuitry is located.
$300+ for repair.
